In Utah, dense populations of codling moth and Western cherry fruit fly represent constant and substantial threats to tree fruit production. Non-uniform or otherwise inadequate spray coverage can greatly reduce treatment efficacy. Measurements of spray coverage were made using water-sensitive cards affixed at various positions in the tree canopy. A conventional rear air-blast sprayer and a tower sprayer were used to deliver a high water volume/acre (200 gpa) and a low volume/acre (100 gpa). The degree of coverage on the water-sensitive cards was greater in the plots sprayed with the tower sprayer, and the higher volume/acre afforded better coverage than the lower volume/acre, though there was much variability within the canopy.
